Bradley Main cannon not doing damage?

Hi Please can you help - I have checked the documentation and updated the config like it says in updates but Bradleys big cannon still doesnt hurt players. The machine gun damages them but the main cannon doesnt? Please can you have a look at my config and let me know where I am going wrong? My server is PVP running TruePVE.

Thank you

as I stated in the previous thread Bradley should be lowercase
